Question 992784
Hi there,
Dwayne's garden is an isosceles triangle.
Two equal sides (and two equal angles)
Length of an equal side = 'x'
Length of other side(s) = x + 4
Perimeter = the 3 sides added together.
49 = x + x  + (x + 4)
49 = x + x  + x + 4
Collect like terms
3x = 49 - 4
3x = 45
x = 15.
Two equal sides = 15 ft
Third side = 19 ft
Hope this helps :-)
